TECHNICAL FIELD

[0001] The application belongs to the technical field of waste gas treatment, and particularly relates to a chemical waste gas treatment equipment and a use method thereof. BACKGROUND

[0002] The waste gas generated in the chemical production process has complex components, often contains particulate matter, tar, acid gas, volatile organic compounds and various pollutants, and needs to be filtered and purified through multiple stages to meet the emission standard. In the waste gas treatment system, the filter unit is the core component for intercepting particulate matter and tar, and its performance and maintenance efficiency directly determines the stable operation and emission standard of the entire treatment system. However, there are still some problems in the use of the current waste gas treatment equipment.

[0003] Firstly, the particulate matter and tar in the chemical waste gas are prone to form a stubborn adhesion layer on the surface of the filter material, causing filter material blockage, resistance rise and treatment efficiency decline, and regular maintenance and replacement are required. The traditional waste gas treatment equipment adopts a fixed filter core mounting structure, and the filter core is fixed in the equipment through fasteners such as bolts and pressure plates. The disassembly and assembly are time-consuming and the operation is very complex.

[0004] Secondly, even if the filter material has not reached the service life, the pollutants adhered to the surface will gradually accumulate, causing the filter resistance to rise and the energy consumption to increase. Most of the equipment adopts the mode of "pressure difference alarm and then cleaning". When the filter material pressure difference rises to the set value, the equipment alarms and then cleans. This passive cleaning method causes the cleaning opportunity to lag behind, affecting the filtering treatment effect. SUMMARY

The outer end of the striking rod contacts the surface of the filter material plate. A second gear is fixedly connected to one end of the short rod extending into the inner cavity of the rotating ring, and the outer ring of the second gear extends out of the rotating ring. A gear ring is fixedly connected to the inner cavity of the main body at a position outside the rotating ring, and the outer ring of the second gear meshes in the tooth groove of the gear ring.

[0013] In a preferred embodiment, the drive unit further includes a mounting shell, which is fixedly mounted on the lower end of the main body. An electric guide rail is fixedly mounted on the right side of the inner cavity of the mounting shell. A motor is fixedly mounted on the slider inside the electric guide rail. A third gear is fixedly connected to the output shaft of the motor. The outer ring of the third gear meshes with the outer ring of the first gear.

[0014] In a preferred embodiment, the outer ring of the rotating ring has a groove, and a toothed ring is fixedly connected in the groove.

A fourth gear is rotatably connected to the lower left side of the main body. Both the lower end of the fourth gear and the lower end of the gear shaft are fixedly connected to sprockets. The outer rings of the two sets of sprockets are meshed with toothed chains.

[0015] A method of using a chemical waste gas treatment device, applicable to any of the above-mentioned chemical waste gas treatment devices, comprising: S1: Exhaust gas purification. After the exhaust gas enters the main body, the spray ring draws liquid from the lower end of the inner cavity of the main body and sprays out water mist, which mixes with the exhaust gas, adsorbs pollutants in the exhaust gas, and purifies it. Then the gas is discharged after being filtered by two sets of filter media plates. S2: Vibration cleaning. Under normal conditions, the filter media can be cleaned periodically by vibration. At this time, the motor moves upward, driving the third gear to connect with the gear shaft. The gear shaft drives the rotating ring and the impact rod to rotate, causing the impact rod to slide in the gear ring to form a rotation, continuously impacting the filter media for vibration cleaning. S3: Scraping and cleaning. After multiple vibration cleaning cycles, scraping and cleaning can be performed periodically. At this time, the motor moves downward, driving the third gear to connect with the rotating rod. The rotating rod will then drive the scraper to rotate, scraping and cleaning the surface of the filter media plate, removing and unblocking the dirt that cannot be cleaned by vibration cleaning. S4: Replace the filter media. After multiple scraping and vibration cleanings, the filter media should be replaced regularly. At this time, hold the pull rod and handle to move the pull rod and drive the limit block down to release the lock between the filter media plate and the main body. Then pull the filter media plate outward to remove it from the main body. The dirt on the plate will fall into the lower end of the inner cavity of the main body. After cleaning, insert the new filter media plate into the main body.

[0016] The technical effects achieved by this invention are as follows: The disassembly and assembly part of the present invention enables quick replacement of filter media plates, simplifies the operation process, and improves efficiency. When too many impurities accumulate on the filter media plates, first stop the exhaust gas from entering, then grip the handle to move the pull rod outward. The pull rod will drive the limit block to retract into the filter media plate to release the fixation of the filter media plate. Then, pull the outer handle to pull the filter media plate out of the main body, and then replace the filter media plate. The cleaning and driving units of this invention enable both vibration cleaning and scraping cleaning of the filter media, and can be switched at will to improve the smooth flow of exhaust gas treatment. When cleaning of the filter media is required, the motor rises, driving the third gear to connect with the gear shaft. The motor then drives the gear shaft to rotate, causing the rotating ring to rotate, which in turn causes the impact rod to rotate within the gear ring, forming a self-rotation. The rotating impact rod continuously strikes the filter media for vibration cleaning. If a stronger cleaning force is required, the motor descends, causing the third gear to connect with the rotating rod. At this time, the rotating rod drives the scraper to rotate, scraping away the substances attached to the filter media to avoid affecting the ventilation effect of the filter media. The spray ring and filter plate of the present invention can spray and filter the exhaust gas to ensure the effect of exhaust gas treatment. When chemical exhaust gas enters the main body, the spray ring will draw up the purification liquid and spray out water mist to spray and purify the exhaust gas. The purified exhaust gas will enter the filter plate for filtration and then be discharged. Attached Figure Description

[0022] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale.

[0023] Please see the appendix Figures 1 to 11 As shown, this is the first embodiment of the present invention, which provides a chemical waste gas treatment device, including: The main body 10 has a spray ring 13 fixedly connected to its inner cavity; The disassembly and assembly part 20 includes a filter plate 21, which is inserted into the inner cavity of the main body 10. A handle 24 is connected to the front of the filter plate 21, and a pull rod 25 is provided inside the handle 24. The upper end of the filter plate 21 is rotatably connected to a limit block 27 through a torsion spring shaft, and the limit block 27 is connected to the pull rod 25. The cleaning unit 30 includes a rotating rod 31, which is rotatably connected to the inner cavity of the main body 10. A scraper 32 is fixedly connected to the outer ring of the rotating rod 31. A rotating ring 34 is rotatably connected to the inner cavity of the main body 10. A striking rod 36 is provided on the inner ring of the rotating ring 34. A toothed ring 38 is connected to the inner cavity of the main body 10. The striking rod 36 is connected to the toothed ring 38. The drive unit 40 includes a motor 43, which is located below the main body 10. The output shaft of the motor 43 is connected to a third gear 44, which is connected to a rotating rod 31. A gear shaft 46 is connected to the left side of the main body 10, which is connected to a rotating ring 34 and is located above the third gear 44. The cleaning unit 30 is divided into two states according to the operation of the drive unit 40. In the first state, the motor 43 remains in its original state, driving the rotating rod 31 and the scraper 32 to rotate. In the second state, the motor 43 rises and drives the third gear 44 to connect with the gear shaft 46. At this time, the gear shaft 46 drives the rotating ring 34 and the impact rod 36 to rotate, causing the impact rod 36 to slide in the gear ring 38 to form a rotation.

[0024] It should be noted that, in order to ensure the stable operation and use of the device, the main body 10 should be equipped with electrical control components and compatible cables to supply power to the various components inside the device and control their stable operation.

[0025] In this embodiment, during use, chemical waste gas enters the main body 10, is purified by spraying from the spray ring 13 and filtered by the filter plate 21 before being discharged. When cleaning of the filter plate 21 is required, the motor 43 rises, driving the third gear 44 to connect with the gear shaft 46. Subsequently, the motor 43 drives the gear shaft 46 to rotate, causing the rotating ring 34 to rotate, making the impact rod 36 rotate within the gear ring 38, forming a rotation. The rotating impact rod 36 continuously impacts the filter plate 21 for vibration cleaning. If a stronger cleaning force is required, the motor 43 will descend, causing the third gear 44 to connect with the rotating rod 31. At this time, the rotating rod 31 will drive the scraper 32 to rotate, scraping off the substances attached to the filter plate 21 to avoid affecting the ventilation effect of the filter plate 21. If the blockage persists after multiple cleanings, or if there is an excessive buildup of impurities on the filter plate 21, first stop the exhaust gas from entering. Then, grip the handle 24 to move the lever 25 outward. The lever 25 will cause the limit block 27 to retract into the filter plate 21, releasing the filter plate 21 from its fixation. Then, pull the handle 24 outward to pull out the filter plate 21 for replacement.

[0026] Secondly, please refer to it again. Figures 1 to 2 An air inlet 11 is provided in the center of the front of the main body 10, and an air outlet 12 is provided in the center of the upper end of the main body 10. A spray ring 13 is fixedly connected to the middle of the inner cavity of the main body 10. A water pump 14 is fixedly installed in the middle of the right side of the main body 10. The inlet and outlet of the water pump 14 are both connected to water pipes 15. The water pipe 15 at the inlet extends into the lower end of the inner cavity of the main body 10, and the water pipe 15 at the outlet extends into the middle of the inner cavity of the main body 10 and communicates with the spray ring 13.

[0027] It should be noted that the lower end of the spray ring 13 is connected to multiple spray heads, which are used to atomize the liquid and improve the effect of exhaust gas purification. The lower end of the inner cavity of the main body 10 should be filled with purification liquid for adsorption and purification in contact with the exhaust gas; Both the air outlet 12 and the air inlet 11 are equipped with flanges and sealing rings to facilitate subsequent connections and to improve the sealing effect. The main body 10 should have an inspection port on its side and a drain outlet at the bottom to facilitate the subsequent treatment of internal dirt and sewage.

[0028] In this embodiment, during use, exhaust gas enters the inner cavity of the main body 10 through the air inlet 11. At this time, the water pump 14 starts, drawing the purified liquid at the lower end of the inner cavity of the main body 10 through the water pipe 15 at the inlet and delivering it to the spray ring 13 through the water pipe 15 at the outlet. The liquid is atomized into fine droplets by the spray head, making full contact with the exhaust gas entering from the air inlet 11, thus achieving preliminary purification. The purified gas continues to move upward and is finally discharged through the air outlet 12.

[0029] Secondly, please refer to it again. Figures 3 to 5 The upper front and rear sides of the main body 10 are provided with through grooves, and filter media plates 21 are movably inserted into the through grooves. The adjacent sides of the two sets of filter media plates 21 are fixedly connected with connecting blocks 22, and the adjacent filter media plates 21 are provided with connecting grooves 23 at the corresponding positions of the connecting blocks 22. A handle 24 is fixedly connected to one end of the filter plate 21 facing the outside of the main body 10. A pull rod 25 is slidably connected to the inner cavity of the handle 24. A spring 26 is fixedly connected to the side of the pull rod 25 facing the outside of the main body 10. The other end of the spring 26 is fixedly connected to the middle of the inner cavity of the handle 24. Limiting blocks 27 are rotatably connected to both the upper and lower sides of the filter plate 21 through torsion spring shafts. A pull rope 28 is fixedly connected to the middle of the lower end of the limiting block 27. The other end of the pull rope 28 passes through the filter plate 21 and is fixedly connected to the middle of the pull rod 25.

[0030] It should be noted that the connecting blocks 22 on the two sets of filter media plates 21 are staggered, and the corresponding positions of the connecting blocks 22 are provided with matching connecting grooves 23, and the connecting parts are provided with sealing layers to ensure the sealing effect. The torsion spring shaft connected to the limiting block 27 always drives the limiting block 27 to rotate upward under normal conditions, and the inner cavity of the main body 10 has a matching groove at the position where the limiting block 27 extends, so that the limiting block 27 can be smoothly inserted into the main body 10. The parts of the filter plate 21 that come into contact with the main body 10 are all equipped with sealing rings to ensure a sealing effect.

[0031] In this embodiment, after being purified by spraying, the exhaust gas passes through two sets of filter media plates 21 for filtration. When it is necessary to disassemble and replace the filter media plates 21, the operator can grasp the handle 24 and pull the lever 25 outward. As the lever 25 slides within the handle 24, it compresses the spring 26 and pulls the limiting block 27 through the pull rope 28, causing it to retract from the main body 10 and releasing the limiting fixation of the filter media plates 21. Then, the operator can pull the handle 24 to pull the filter media plates 21 out of the main body 10. Subsequently, the operator can insert a new filter media plate 21 into the main body 10.

[0032] Secondly, please refer to it again. Figures 6 to 9 The rotating rod 31 is rotatably connected to the lower end of the inner cavity of the main body 10 through a sealed bearing. The upper outer ring of the rotating rod 31 is rotatably connected to the middle position of the two sets of filter media plates 21. A scraper 32 is fixedly connected to the upper end of the rotating rod 31. The blade of the scraper 32 is attached to the surface of the filter media plate 21. The lower part of the rotating rod 31 that extends out of the main body 10 is fixedly connected to the first gear 33. An annular groove is provided at the upper end of the inner cavity of the main body 10, and a rotating ring 34 is rotatably connected in the annular groove. Multiple sets of short rods 35 are rotatably connected to the inner cavity of the rotating ring 34 through a sealed bearing. A striker 36 is fixedly connected to one end of the short rod 35 extending out of the rotating ring 34. The outer end of the striker 36 contacts the surface of the filter plate 21. A second gear 37 is fixedly connected to one end of the short rod 35 extending into the inner cavity of the rotating ring 34, and the outer ring of the second gear 37 extends out of the rotating ring 34. A gear ring 38 is fixedly connected to the inner cavity of the main body 10 at the position outside the rotating ring 34. The outer ring of the second gear 37 meshes in the tooth groove of the gear ring 38.

[0033] It should be noted that sealing rings are provided at the contact points between the rotating rod 31 and the filter media plate 21, and a sealing bearing is fixedly connected in the gap of the sealing ring. A sealing gasket is provided on the outer ring of the sealing bearing, and the sealing gasket contacts the filter media plate 21. This is intended to ensure sealing while not affecting the normal rotation of the rotating rod 31. The scraper 32 is provided in three sets, which are respectively set on the upper and lower sides and in the gap of the upper and lower filter media plates 21. The purpose is to scrape off the dirt on the surface of the filter media plates 21 and avoid large-area blockage that affects the ventilation effect. The impact bar 36 consists of three sets of rubber bars, designed to vibrate and clean the filter media plate 21 by impacting it. The portion of the rotating ring 34 near the gear ring 38 has a through groove, through which the second gear 37 meshes with the gear ring 38.

[0034] In this embodiment, after the first gear 33 is driven to rotate by the drive unit 40, it will drive the rotating rod 31 and the scraper 32 to rotate synchronously. Since the scraper 32 is respectively attached to the upper and lower surfaces of the upper and lower filter media plates 21 and the gap between the two sets of filter media plates 21, when the scraper 32 rotates with the rotating rod 31, its blade can scrape off the dust, oil and other dirt attached to the surface of the filter media plate 21, effectively preventing the filter pores of the filter media plate 21 from being blocked over a large area. After the rotating ring 34 is driven to rotate by the drive unit 40, it will drive the impact rod 36 on it to rotate synchronously. At the same time, the second gear 37 will rotate in a ring within the gear ring 38 and rotate on its own axis due to meshing. The rotating second gear 37 will drive the short rod 35 and the impact rod 36 to rotate on their own axes. This causes the impact rod 36 to repeatedly strike the filter media plate 21, forming a vibration cleaning.

[0035] Please refer to it again. Figures 6 to 7 , Figures 9 to 11 The drive unit 40 also includes a mounting shell 41, which is fixedly mounted on the lower end of the main body 10. An electric guide rail 42 is fixedly mounted on the right side of the inner cavity of the mounting shell 41. A motor 43 is fixedly mounted on the slider inside the electric guide rail 42. A third gear 44 is fixedly connected to the output shaft of the motor 43. The outer ring of the third gear 44 meshes with the outer ring of the first gear 33. The outer ring of the rotating ring 34 has a groove, and a toothed ring 45 is fixedly connected in the groove. The left side of the main body 10 is rotatably connected to a gear shaft 46 via a ball bearing. The outer ring of the gear shaft 46 passes through the main body 10 and meshes with the toothed ring 45. The lower left side of the main body 10 is rotatably connected to a fourth gear 47 via a ball bearing. The lower end of the fourth gear 47 and the lower end of the gear shaft 46 are both fixedly connected to sprockets 48. The outer rings of the two sets of sprockets 48 are meshed with toothed chains 49.

[0036] It should be noted that the electric guide rail 42 is an electrically driven guide rail that only moves up and down, and the slider inside the electric guide rail 42 is provided with a mounting plate, and the motor 43 is fixedly connected to the mounting plate. The third gear 44 can mesh with the fourth gear 47; The upper outer ring of the gear shaft 46 is provided with two sets of gear structures, and both sets of gear structures penetrate the main body 10 and mesh with two sets of gear rings 45 respectively. Preferably, to ensure the stable operation of the toothed chain 49, a protective shell can be provided on the outer ring of the toothed chain 49 and the protective shell can be fixedly connected to the inside of the main body 10 or the mounting shell 41 to prevent the toothed chain 49 from falling off (this is a common technical structure in the prior art, and will not be described in detail here).

[0037] In this embodiment, under normal conditions, the third gear 44 meshes with the first gear 33. When vibration cleaning is required, the electric guide rail 42 drives its internal slider and motor 43 to move upward. During this process, the third gear 44 gradually disengages from the first gear 33 and meshes with the fourth gear 47. At this time, the motor 43 drives the third gear 44 and the fourth gear 47 to rotate. The sprocket 48 at the lower end of the fourth gear 47 drives the sprocket 48 at the lower end of the gear shaft 46 to rotate synchronously through the toothed chain 49, thereby causing the gear shaft 46 to rotate. The gear shaft 46 then drives two sets of toothed rings 45 to rotate. The rotation of the toothed rings 45 causes the corresponding components connected to them to vibrate, thereby realizing the vibration cleaning function for specific parts of the equipment. When scraping and cleaning are required, the electric guide rail 42 drives the slider to drive the motor 43 to reset downwards, and the third gear 44 re-engages with the first gear 33. At this time, the motor 43 drives the third gear 44 and the first gear 33 to rotate, and the first gear 33 drives the rotating rod 31 to rotate. The rotating rod 31 drives the scraper 32 to rotate to perform scraping and cleaning operations. Example 2

[0038] A method of using a chemical waste gas treatment device, characterized in that: it is applicable to any of the above-mentioned chemical waste gas treatment devices, comprising: S1: Exhaust gas purification. After the exhaust gas enters the main body 10, the spray ring 13 draws the liquid at the lower end of the inner cavity of the main body 10 and sprays out water mist, which mixes with the exhaust gas, adsorbs the pollutants in the exhaust gas, and purifies it. Then the gas is discharged after being filtered by two sets of filter plates 21. S2: Vibration cleaning. Under normal conditions, the filter media plate 21 can be cleaned by vibration periodically. At this time, the motor 43 moves upward, driving the third gear 44 to connect with the gear shaft 46. The gear shaft 46 drives the rotating ring 34 and the impact rod 36 to rotate, causing the impact rod 36 to slide in the gear ring 38 to form a rotation, and continuously impacting the filter media plate 21 for vibration cleaning. S3: Scraping and cleaning. After multiple vibration cleanings, scraping and cleaning can be performed periodically. At this time, the motor 43 moves downward, driving the third gear 44 to connect with the rotating rod 31. The rotating rod 31 will drive the scraper 32 to rotate, scraping and cleaning the surface of the filter plate 21, and scraping and unblocking the dirt that cannot be cleaned by vibration cleaning. S4: Replace the filter media. After multiple scraping and vibration cleanings, the filter media should be replaced regularly. At this time, hold the pull rod 25 and handle 24 to move the pull rod 25, which will cause the limit block 27 to descend and release the lock between the filter media plate 21 and the main body 10. Then pull the filter media plate 21 out to remove it from the main body 10. The dirt on the plate will fall into the lower end of the inner cavity of the main body 10. After cleaning, insert the new filter media plate 21 into the main body 10.

[0039] In this embodiment, during use, the S2 and S3 processes should be performed intermittently, for example, performing S2 three times and then performing S3 once, to avoid affecting the service life of the filter material.

[0040] The working principle of this invention is as follows: During use, exhaust gas enters the inner cavity of the main body 10 through the air inlet 11. At this time, the water pump 14 starts to draw up the purified liquid and sends it to the spray ring 13 to atomize into water mist, which fully contacts the exhaust gas entering from the air inlet 11 to achieve preliminary purification. Then, after being filtered by the filter plate 21, it is discharged from the air outlet 12. When it is necessary to disassemble and replace the filter plate 21, the operator can hold the handle 24 and pull the pull rod 25 outward. The pull rope 28 pulls the limiting block 27 to rotate, causing it to retract from the main body 10, releasing the limiting fixation of the filter plate 21. Then, the filter plate 21 can be pulled out of the main body 10 for replacement. When it is necessary to vibrate and clean the filter plate 21, the electric guide rail 42 drives the motor 43 to move upward, so that the third gear 44 and the fourth gear 47 mesh. Then, the motor 43 drives the third gear 44 and the fourth gear 47 to rotate. The sprocket 48 at the lower end of the fourth gear 47 drives the sprocket 48 at the lower end of the gear shaft 46 to rotate synchronously via the toothed chain 49, thereby causing the gear shaft 46 to rotate. The gear shaft 46 then drives the two sets of toothed rings 45 to rotate, and the rotating ring 34 drives the impact rod 36 to rotate synchronously. At the same time, the second gear 37 rotates in a ring within the toothed ring 38 and rotates on its own axis due to meshing. The rotating second gear 37 drives the short rod 35 and the impact rod 36 to rotate on their own axes. This causes the impact rod 36 to repeatedly strike the filter media plate 21, creating vibration cleaning. When scraping cleaning is required, the electric guide rail 42 drives the motor 43 to reset downwards, and the third gear 44 re-meets the first gear 33. At this time, the motor 43 drives the third gear 44 and the first gear 33 to rotate. The first gear 33 then drives the rotating rod 31 to rotate, and the rotating rod 31 drives the scraper 32 to rotate for scraping cleaning.
